.There have been known various hair clips for the purpose of pin-curlingof hair. However, these known hair clips have been ordinarily used atthe normal ambient temperature and, for this reason, it has required along time to make the intended curl formed with such known clips. Thus,their usage has been inconvenient in that, forexample, the clips have tobe set in the users hair while the user is in bed.

It is, therefore, an object of the present invention to provide a hairclip which has no such defect as described above. Animportant feature ofthe present invention resides in that the heat-storing member providedat the inner surface of the clipping plate is brought into v directcontact with heating means prepared separately from the clip and theclip is used afterbeing heated. This feature permits the curl to beformedin a shorter time.

Another important feature of the hair clip according to the presentinvention is that the respective clipping plates are designed in such amanner that one of the clipping plates has the heat-storing member atits inner surface, a part of which member protrudes from the surface andthe other part is merged in the plate, and the other clipping plate isprovided with a groove into which the protruding extruded part of theheat-storing member will engage. This causes the heat-storing member tobe effectively brought into contact with the heating means so that thehair clip will store the heat quickly and on the other hand theheat-storing member itself will discharge the heat gradually.

In another aspect of the present invention, the clipping plates areformed substantially in a disk shape so that-the hair curled in a spiralwill be effectively held in the-clip, so that the heat will beeffectively utilized.

The heating device for use with the hair clip of the present inventionis an electric heating device having a heating member extendingtherefromto allow the hair clip to hold the member and to be heatedthereby.

In one of the aspects of the heating device according to the presentinvention, the device is characterized in that the heating member of thedevice is provided with a proper clearance from an engaging plate formedat a part of the device case to establish a close contact of theheat-storing member of the clip with the heating member, so that thehair clip holds the heating member to be heated. v

In another aspect of the heating device for the hair clip according tothe present invention, the electric heating device is provided with aprojected metal pin for heating tubular hair curlers, so that theheating of the heating member for the hair clip and of the metal pin forheating the hair curlers is simultaneously carried out with the sameelectric heating device.

Further in another aspect of the present invention, the heating deviceis provided with a flat plate heating member for the clip at the forwardend of the heating pin for the tubular hair curler, so that simultaneousheating of the tubular hair curler and the hair clip can be performed bymeans of such heating pin.

The present invention shall now be explained with reference to theaccompanying drawings, in which:

FIG. 1 is a perspective view of an embodiment of the hair clip accordingto the present invention.

FIG. 2 shows a section of the hair clip taken along the line X-X in FIG.'1.

FIG. 3 is a cross section taken along the line Y--Y in FIG. 1.

FIG. 4 is a perspective view showing another embodiment of the hair clipaccording'to the presentinvention. v

FIG. 5 shows a section of the hair clip of FIG. 4 taken along the lineZ-Z in the same.

FIG. 6 shows a cross sectional view of an embodiment of a heating devicefor the hair clip according to the present invention. v

FIG. 7 show a cross sectional view of another embodiment of the heatingdevice for the hair clip.

Referring to the drawings, there are shown embodiments of the hair clipsaccording to the present invention for winding hair into .a spiral shapeand pin-curling the same. In the drawings, a pair of upper and lowerclipping plates vA and B, made of a molded plastic synthetic resin, arehinged together by means of a pin 3 inserted through'respective holes inreceiving-pieces 1 and 2 projecting from the plates A and B,respectively. The plates A-and B are caused to be pressed against eachother by means of a spring 4 mounted at the hinged end of the clip. Inthe embodiment shown in FIGS. 1-3, the upper clipping plate A, formed ina rectangular shape with a synthetic resin, is provided with alongitudinallyextending heat-storing member C made of a metal platehaving a large heat capacity and readily heatable. The member C islocated at the center of the plate Afor clipping purposes with bothlongitudinal side edges embedded in the plate 'A so as to be fixedthereto and its central part 5 protruding from the plate. The lowerclipping plate B is similarly formed in from touching the user 5 scalpwith its whole surface when the clip is set to the hair, so that theuser will not sense any unpleasant heat at the scalp.

In the alterative embodiment as shown in FIGS. 4 and 5, the clippingparts of the clipping plates A and B are formed substantially in a diskshape. At the inner surface of the clipping part of the upper plate A, adiskshaped heat-storing member C is secured, so that a strand of hairswound in a spiral can be held between the disk-shaped upper and lowerclipping plates A and B in a flat manner and heated therebetween.

The heat-storing member C may be, rather than a metal plate, formedfroma synthetic resin of the type that is high in thermal conductivityand heat capacity, into which powdery or fibrous glass, aluminum,asbestos and the like are mixed. 1

FIG. 6 shows an exemplary electric heating device according to thepresent invention, which is provided with heating pins for the haircurlers. A casing G is opened at the top of the case body K, whichopening is partially closed with a lid 8 having a slit 9 and an engagingplate 10 downwardly extended with aninclination casing G, a heatgenerating means E comprising a stack of a heater base J and a heater1-! of an electric heat generating material heats a holding fixture 12made of a metal plate having a flat clip heating member or plate L bentfrom oneend thereof. The clip heating plate L extends upwardly past andis spaced from the engaging plate 10. Upward extensions of the edgeportions of the plate 12 are folded over the stack formed by members Jand H to integrally clamp such stack to the plate 12. Screws 13 passedthrough the over-folded portions of the stack secure E to the bottom ofthe casing G. A plurality of heating members or pins 11 of columnarshape are formed integrally with the base J so as to extend upwardlythrough the opening of the casing G.

The heater H is supplied with electric power through a connecting cordnot shown and heats the heating base J and heating plate L thermallycoupled thereto. Tubular hair curlers M having a heat-storing substance16 sealed in the space between a metal inner tube 14 and an outer tube15 of a plastic material are fitted over the heating pins 11 so that theinner tubes 14 contact the pins 11 to heat the curlers. The beforementioned hair clip is placed over the heating plate L in such a mannerthat its upper clipping plate v A is inserted into the clearance betweenthe plate L and the engagingplate 10, so that the forward end of theplate A engages the engaging plate 10 to automatically earn the entirearea of the heat-storing member C of the clip against one side surfaceof the heating plate L. Both clipping plates A and B thus grip theheating plate L and are heated by the latter.

In the alterative aspect of the heating device as shown in FIG. 7, aflat-shaped heating plate L is formed integrally at the upper end ofeach columnar pin 11 of the heating body E encased and fixed inside thecase body K. In this arrangement, the device is adapted to heat the haircurlers M at the columnar parts of the heating pins 11 and also to heatthe hair clip on' any of the flat-shaped heating plates L.
